I am going to put my tin hat on here but I went back and read all your previous posts Renee just to get a picture and did find it a bit scary to see you doing so much planning when it clearly you are new to dogs. I personally would forget any breeding plan etc for now at least and put in a good training plan. Join your breed club and speak to your puppies breeders as the oldest one is still a puppy herself. Learn about the breed. You will need to wait and see how good your dogs turn out. Well that is what a reputable breeder would do so that is the advice any dog lover should give.
Without any knowledge how can you make a correct moral decision whether either dog is suitable to breed from. Any good breeder will tell you a line of champions in a pedigree doesn't mean that much. 2 different lines mixed may make a terrible litter.
I find it hard sometimes that people ask questions but only want the answers they want to hear. Any Dog owner/breeder is going to ask why you want to breed if you say you bought the dog for a companion for your other then within 48 hours you have a breeding plan people are going to ask questions as to why.
You have to gain knowledge in your breed before you decide to breed yourself it is not an easy thing to do, nobody is saying you need to be an expert, we all have to learn , however training dogs , getting to know your breed should all be done first. You will find the answer to your question in some of your breed books which you may even be able to pick up at the library.
Good luck. Hope you new puppy has settled down now.
I am sorry I didn't give you a one answer reply to your question but most people won't.
